Title: Negative electrode for lithium secondary battery and its manufacture
Inventor: TSUKAMOTO HISASHI
IPC: H01M4/587
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To improve low temperature performance and high temperature storage characteristics of a lithium secondary battery. SOLUTION: Graphite is heated in a non-oxide atmosphere to perform an activation treatment to remove oxygen from its surface, and then an organic material is introduced under an inert atmosphere to combine carbon to a surface of an activated graphite. Thereby, a thin film containing crystalline low carbon and carbonic compounds are formed. If acentonitrile vapor is used as the organic material introduced, CxN is formed on a surface of the graphite to obtain more superior characteristics.

Title: Interference apparatus
Inventor: HIRANO ISUKE
IPC: G01J9/02
Filed: 1987-06-10
Abstract: PURPOSE:To enable measurement of coherence of light with single observation, by arranging a plurality of optical delay paths varied in the optical path length in one of two split optical paths of a Michelson's interferometer. CONSTITUTION:Light 1 generated with a single phenomenon of a light source or light is turned with a collimation lens 2 into a parallel luminous flux and the light divided in two with a half mirror 3 and reflected is reflected 4 in the original direction and transmitted through the half mirror 3 to reach a 1-D or 2-D detector 7, when a wave front 9 thereof becomes planar. The beam transmitted through the half mirror 3 out of the two split 3 beams is transmitted through and reflected 5 with an echelon 8, again, reaches the echelon 8 and the half mirror 3 and reflected to reach the detector 7. At this point, the wave front 10 shows a form of a staircase. The two wave fronts 9 and 10 interfere 7 with each other to form an interference fringe with the sharpness thereof varying corresponding to the coherence of the light 1. As the optical path length in steps of the echelon 8 is known, the coherence of the light can be detected by determining the sharpness of the interference fringe corresponding to the steps.

Title: Water supply controller for boiler
Inventor: SANO FUMIYASU
IPC: F22B35/00
Filed: 1994-06-27
Abstract: PURPOSE:To prevent transient unstable control at the time of cutting OFF a load by outputting a correction signal which is slightly raised instead of an abruptly reducing main steam flow rate signal at the time of cutting OFF the load and gradually decreased after a predetermined delay time. CONSTITUTION:At the time of cutting OFF a load, a switching unit 9 is conducted at b-c according to a signal from a logic circuit 16 which receives a load cut-off signal, and a main steam flow rate signal 01s is abruptly reduced. However, it is delayed by a delay calculator 6, a correction signal for correcting the reduced pressure of a boiler from a signal generator 7 is added, and an output signal 15s from a switching unit 11 is continuously increased. Thus, the reduced amount of actual supply water quantity due to the high main steam pressure at the time of cutting OFF the load is supplemented. After fuel is throttled until the balance of a turbine side with the load at the time of cutting OFF the load is obtained at the boiler side, this state is held until main steam is stabilized. Then, the output 15s of the unit 11 is gradually decreased at a predetermined change rate, and approached to the signal 01s.
